[CentOS] why I can't start centos 7.6 sometimes

Hi,


I make centos 7.6 usb-disk, via which CentOS 7.6 is installed. But sometimes CentOS 7.6 can't start correctly, and stopped with the following message:


                               led to map dmar1
[     1.881791] nouveau 0000:01:00.0: disp: conn 01:0130: func 00 lookup failed,



What's the problem with CentOS?


Thanks!


Regards


Andrew
